"Peace is a lie, there is only passion.
Through passion I gain strenght.
Through strenght I gain power.
Through power I gain victory.
Through victory my chains are broken.
The force shall free me." -Code of the Sith

I was going to say something crude, along the lines that involved the sucker tipped fingers and multiple females, but i daresay i might upset a few people. So i'll say that being a rodian has its positive sides.

Again, this isn't a direct answer (it has to do with the wording of your question), but opinion about the most loserish races in Star Wars:
1. Gungan.
2. Yevethan.
3. Hutt.
4. Aqualish.
5. Nemoidian.
6. Almost all other near-humans except for the Chiss (seems too Star Trekkie having 'aliens' who look practically human).
7. Wookiees (they also have been in contact with the main galactic civilization for some time and have remained generally un-advanced).
8. Twi'lek (they've been integrated into galactic civilization for so long and yet they are still a bunch of slaves and sycophants?) Not trying to be antagonistic--since a lot of people here seem to admire Twi'leks--but this is opinion about them.
